It is called impossible, according to current theory.
Gradualism.
Because it was Darwin who made it a scientifically plausible explanation, by providing a mechanism by which evolution could occur....Natural Selection.
Evolution occurs in population not in an individual.
Yes. Evolution ocurred in all geologic periods.
Punctuated equilibrium is the model of evolution in which periods of rapid change occur interspersed with long periods of stability. This theory suggests that species evolve quickly in short bursts of rapid change followed by extended periods of little or no change.
Down Syndrome is a the addition of an extra chromosome and not really related to evolution. It is more of a genetic mutation that causes this event to occur.
You do not allow evolution to occur, for you are evolution in selective breeding.
The more variation there is in a group of specimens, the more evolution can occur between them.
During evolution, chromosomal cariation in structure cannot occur due to
For a mutation to affect evolution, it must occur in the DNA of reproductive cells (sperm or egg cells) so that it can be passed on to offspring. Mutations that occur in somatic cells (non-reproductive cells) do not directly impact evolution as they are not inherited by future generations.
It already has in some instances
Selective Breeding of course!
